The Whitewater-Baldy Fire Complex continued to burn in far western New Mexico on 26 May 2012. A night-time AWIPS image comparison of Suomi NPP VIIRS 11.45 Âµm IR and 3.74 Âµm shortwave IR data (above) demonstrated how the shortwave IR channel is much more sensitive to the presence of hot fire pixels (red to yellow to black color enhancement). The active fires were located along the perimeter of the large fire complex.

The corresponding Suomi NPP VIIRS 0.7 Âµm “Day/Night Band” image (below) revealed a very distinct bright “ring of fire” signature from these actively burning perimeter fires. Both the Day/Night Band and the shortwave IR signatures looked notably larger on this day than they did on 23 May.

During the following afternoon hours, a Suomi NPP VIIRS 0.64 Âµm visible channel image (below) showed that a long smoke plume continued to be blown toward the northeast, as was seen on a number of previous days.
